3.3^2 means 3.3 times itself 2 times or 3.3 times 3.3 or (use calculator)10.89
smaller powers (that's what 3.3^2 is, it means 3.3 to the second power) sometimes use different words to denote powers exg
x^2=x squared (square=2dimentionsl)
x^3=x cubed (cube=3 dimentionsl)
then x^4=x to the fourth, and so on
fifth, sixth, tecnth
Let
x---------> the number
we know that
[9+2x]*4=4x+12
36+8x=4x+12
8x-4x=12-36
4x=-24
x=-24/4
x=-6
the answer is
-6
Step-by-step explanation:
f°g=
if the denominator is zero the number is undefined which makes it not in the domain of the function
set 
equal to 0
the values for x is 0 or 6
so the only value that is not in the domain of f°g is 0 and 6
Hope that helps :)
